Early Diagnosis and Treatment of Type 2 Diabetes Reduces Risk of Heart Disease, Death

A delay of three years in diagnosis and treatment of type 2 diabetes increases the risk of cardiovascular diseases by 22.4%.

The early detection of Type 2 diabetes followed by early treatment can reduce the risk of heart disease and death, says a new research.

In a study conducted at the University of Michigan Medical School and the University of Cambridge, it was analyzed that the early screening of Type 2 diabetes could lead to substantial health benefits. This approach revealed that screening followed by treatment led to a reduced risk of cardiovascular disease or death within a five-year follow-up period when compared to patients having no screening.

Globalization and changing lifestyles has made diabetes very common in developing countries so much so that India is known as the Diabetes Capital of the World.

Professor William Herman of the University of Michigan said the research showed early identification of diabetes had major health benefits, and supported the introduction of measures such as screening so as to reduce the time between development of Type 2 diabetes and its treatment.

At 10 years after baseline, the simulations predicted that with a delay of three years in diagnosis and treatment, 22.4 percent of those with Type 2 diabetes would experience a cardiovascular disease event, such as stroke or heart bypass surgery. This rose to 25.9 percent with a diagnosis delay of six years.

However, if screening and routine care had been implemented, the simulation predicted only 18.4 percent would experience a cardiovascular disease event at 10 years after baseline. The simulated incidence of all-cause mortality was 16.4 percent with a delay of three years and 18.2 percent with a delay of six years, compared to 14.6 percent for screening and treatment.

Men with multiple wives need higher finances. So they take on extra employment or have the added pressure of traveling daily to urban areas for higher paid work.

This means that over 10 years, the model predicts that for people with undiagnosed Type 2 diabetes, screening would be associated with a 29 percent reduction in relative risk of a cardiovascular disease event, compared with a delay of six years in diagnosis and treatment.

This amounts to a 7.5 percent reduction in the absolute risk of adverse cardiovascular outcome in this population. The comparable change in all-cause mortality was 20 percent relative risk and 3.6 percent absolute risk reduction.
